Operating Manual PMCprimo MC

| 22
Before the CODESYS project starts, all the devices must be operational so that they are
detected by the EtherCAT master.
The address assignment of the network subscribers is performed automatically in the se-
quence of the physical arrangement. The sequence of the inserted devices in the device
tree must match the physical arrangement.
Please note the following during operation:
}
The device sequence may no longer be modified.
}
It is not permitted to add or remove devices.
The PMCprimo MC is an EtherCAT master, which is the only subscriber in the segment that
can actively send an EtherCAT frame; all the other subscribers only forward the frames.
This prevents unforeseeable delays and it guarantees real-time capability.
Bit errors in the transmission are reliably detected in the evaluation of CRC check sums.
Rare interferences can be detected and localised with EtherCAT even if the interference
does not influence the functionality of the machine.

USB
INFORMATION
Use a USB stick with FAT32 formatting.
}
The USB interface is used for data exchange.
}
The data can contain a new firmware with a complete project.
}
Save data from a controller to a USB stick:
– Save data on a USB stick into the following directory: "\PILZ\primoBACKUP\"
}
To save, execute the SP11 command.
}
Save data for device exchange via reset button to USB stick:
– Make sure that the directory "primoBACKUP" does not exist on the USB stick. (avoid
overwriting accidentally)
– Insert USB stick
– Press the RESET button during the boot process until the LEDs flash blue.
}
Copy data stored on a USB stick to the controller:
– Insert USB stick
}
Activate the hardware reset (cold start) by pressing the "RESET" button, see

Depending on the configuration, the device has
}
3 encoder connections X41, X55 and X56 (Mini I/O sockets)
}
2 encoder connections X55 and X56 (Mini I/O sockets) and 1 encoder connection X41 for
Encoder emulation [
